At from the runway the helicopter had a catastrophic forward transmission failure which de-synchronised the tandem rotors, causing the blades to collide. The helicopter crashed into the sea and sank. 43 passengers and two crew members were killed in the crash; one passenger and one crew member survived with wounds.

The Chinook design has evolved through several models over time and has been produced by two companies. Over 850 in total have been completed and flown and kits remain in production in the 21st century. The first Chinook model introduced was the single-seat WT-11, which entered the market in 1983.

Improved and more powerful versions of the Chinook have also been developed since its introduction; one of the most substantial variants to be produced was the CH-47D, which first entered service in 1982; improvements from the CH-47C standard included upgraded engines, composite rotor blades, a redesigned cockpit to reduce workload, improved and redundant electrical systems and avionics, and the adoption of an advanced flight control system.

The counter-rotating rotors eliminate the need for an antitorque vertical rotor, allowing all power to be used for lift and thrust.
